### 3.2
```
~~~~~~~~~~~~~~~~
* **SECURITY ISSUE:** Attempted to make RSA PKCS1v1.5 decryption more constant
time, to protect against Bleichenbacher vulnerabilities. Due to limitations
imposed by our API, we cannot completely mitigate this vulnerability and a
future release will contain a new API which is designed to be resilient to
these for contexts where it is required. Credit to **Hubert Kario** for
reporting the issue. *CVE-2020-25659*
* Support for OpenSSL 1.0.2 has been removed. Users on older version of OpenSSL
will need to upgrade.
* Added basic support for PKCS7 signing (including SMIME) via
:class:`~cryptography.hazmat.primitives.serialization.pkcs7.PKCS7SignatureBuilder`.
.. _v3-1-1:
```
### 3.1.1
```
~~~~~~~~~~~~~~~~~~
* Updated Windows, macOS, and ``manylinux`` wheels to be compiled with
OpenSSL 1.1.1h.
.. _v3-1:
```
### 3.1
```
~~~~~~~~~~~~~~~~
* **BACKWARDS INCOMPATIBLE:** Removed support for ``idna`` based
:term:`U-label` parsing in various X.509 classes. This support was originally
deprecated in version 2.1 and moved to an extra in 2.5.
* Deprecated OpenSSL 1.0.2 support. OpenSSL 1.0.2 is no longer supported by
the OpenSSL project. The next version of ``cryptography`` will drop support
for it.
* Deprecated support for Python 3.5. This version sees very little use and will
be removed in the next release.
* ``backend`` arguments to functions are no longer required and the
default backend will automatically be selected if no ``backend`` is provided.
* Added initial support for parsing certificates from PKCS7 files with
:func:`~cryptography.hazmat.primitives.serialization.pkcs7.load_pem_pkcs7_certificates`
and
:func:`~cryptography.hazmat.primitives.serialization.pkcs7.load_der_pkcs7_certificates`
.
* Calling ``update`` or ``update_into`` on
:class:`~cryptography.hazmat.primitives.ciphers.CipherContext` with ``data``
longer than 2\ :sup:`31` bytes no longer raises an ``OverflowError``. This
also resolves the same issue in :doc:`/fernet`.
.. _v3-0:
```
### 3.0
```
~~~~~~~~~~~~~~~~
* **BACKWARDS INCOMPATIBLE:** Removed support for passing an
:class:`~cryptography.x509.Extension` instance to
:meth:`~cryptography.x509.AuthorityKeyIdentifier.from_issuer_subject_key_identifier`,
as per our deprecation policy.
* **BACKWARDS INCOMPATIBLE:** Support for LibreSSL 2.7.x, 2.8.x, and 2.9.0 has
been removed (2.9.1+ is still supported).
* **BACKWARDS INCOMPATIBLE:** Dropped support for macOS 10.9, macOS users must
upgrade to 10.10 or newer.
* **BACKWARDS INCOMPATIBLE:** RSA
:meth:`~cryptography.hazmat.primitives.asymmetric.rsa.generate_private_key`
no longer accepts ``public_exponent`` values except 65537 and 3 (the latter
for legacy purposes).
* **BACKWARDS INCOMPATIBLE:** X.509 certificate parsing now enforces that the
``version`` field contains a valid value, rather than deferring this check
until :attr:`~cryptography.x509.Certificate.version` is accessed.
* Deprecated support for Python 2. At the time there is no time table for
actually dropping support, however we strongly encourage all users to upgrade
their Python, as Python 2 no longer receives support from the Python core
team.
If you have trouble suppressing this warning in tests view the :ref:`FAQ
entry addressing this issue <faq-howto-handle-deprecation-warning>`.
* Added support for ``OpenSSH`` serialization format for
``ec``, ``ed25519``, ``rsa`` and ``dsa`` private keys:
:func:`~cryptography.hazmat.primitives.serialization.load_ssh_private_key`
for loading and
:attr:`~cryptography.hazmat.primitives.serialization.PrivateFormat.OpenSSH`
for writing.
* Added support for ``OpenSSH`` certificates to
:func:`~cryptography.hazmat.primitives.serialization.load_ssh_public_key`.
* Added :meth:`~cryptography.fernet.Fernet.encrypt_at_time` and
:meth:`~cryptography.fernet.Fernet.decrypt_at_time` to
:class:`~cryptography.fernet.Fernet`.
* Added support for the :class:`~cryptography.x509.SubjectInformationAccess`
X.509 extension.
* Added support for parsing
:class:`~cryptography.x509.SignedCertificateTimestamps` in OCSP responses.
* Added support for parsing attributes in certificate signing requests via
:meth:`~cryptography.x509.CertificateSigningRequest.get_attribute_for_oid`.
* Added support for encoding attributes in certificate signing requests via
:meth:`~cryptography.x509.CertificateSigningRequestBuilder.add_attribute`.
* On OpenSSL 1.1.1d and higher ``cryptography`` now uses OpenSSL's
built-in CSPRNG instead of its own OS random engine because these versions of
OpenSSL properly reseed on fork.
* Added initial support for creating PKCS12 files with
:func:`~cryptography.hazmat.primitives.serialization.pkcs12.serialize_key_and_certificates`.
.. _v2-9-2:
```
### 2.9.2
```
~~~~~~~~~~~~~~~~~~
* Updated the macOS wheel to fix an issue where it would not run on macOS
versions older than 10.15.
.. _v2-9-1:
```
### 2.9.1
```
~~~~~~~~~~~~~~~~~~
* Updated Windows, macOS, and ``manylinux`` wheels to be compiled with
OpenSSL 1.1.1g.
.. _v2-9:
```
### 2.9
```
~~~~~~~~~~~~~~~~
* **BACKWARDS INCOMPATIBLE:** Support for Python 3.4 has been removed due to
low usage and maintenance burden.
* **BACKWARDS INCOMPATIBLE:** Support for OpenSSL 1.0.1 has been removed.
Users on older version of OpenSSL will need to upgrade.
* **BACKWARDS INCOMPATIBLE:** Support for LibreSSL 2.6.x has been removed.
* Removed support for calling
:meth:`~cryptography.hazmat.primitives.asymmetric.x25519.X25519PublicKey.public_bytes`
with no arguments, as per our deprecation policy. You must now pass
``encoding`` and ``format``.
* **BACKWARDS INCOMPATIBLE:** Reversed the order in which
:meth:`~cryptography.x509.Name.rfc4514_string` returns the RDNs
as required by :rfc:`4514`.
* Updated Windows, macOS, and ``manylinux`` wheels to be compiled with
OpenSSL 1.1.1f.
* Added support for parsing
:attr:`~cryptography.x509.ocsp.OCSPResponse.single_extensions` in an OCSP
response.
* :class:`~cryptography.x509.NameAttribute` values can now be empty strings.
.. _v2-8:

Changelog
### 3.0.9
```
Security
- Escape path before evaluating resource rules (thanks to Colby Morgan). Prior to this, flask-cors incorrectly
evaluated CORS resource matching before path expansion. E.g. "/api/../foo.txt" would incorrectly match resources for
"/api/*" whereas the path actually expands simply to "/foo.txt"
```

Changelog
### 1.26.2
```
-------------------
* Fixed an issue where ``wrap_socket`` and ``CERT_REQUIRED`` wouldn't
be imported properly on Python 2.7.8 and earlier (Pull 2052)
```
### 1.26.1
```
-------------------
* Fixed an issue where two ``User-Agent`` headers would be sent if a
``User-Agent`` header key is passed as ``bytes`` (Pull 2047)
```
### 1.26.0
```
-------------------
* **NOTE: urllib3 v2.0 will drop support for Python 2**.
`Read more in the v2.0 Roadmap <https://urllib3.readthedocs.io/en/latest/v2-roadmap.html>`_.
* Added support for HTTPS proxies contacting HTTPS servers (Pull 1923, Pull 1806)
* Deprecated negotiating TLSv1 and TLSv1.1 by default. Users that
still wish to use TLS earlier than 1.2 without a deprecation warning
should opt-in explicitly by setting ``ssl_version=ssl.PROTOCOL_TLSv1_1`` (Pull 2002)
**Starting in urllib3 v2.0: Connections that receive a ``DeprecationWarning`` will fail**
* Deprecated ``Retry`` options ``Retry.DEFAULT_METHOD_WHITELIST``, ``Retry.DEFAULT_REDIRECT_HEADERS_BLACKLIST``
and ``Retry(method_whitelist=...)`` in favor of ``Retry.DEFAULT_ALLOWED_METHODS``,
``Retry.DEFAULT_REMOVE_HEADERS_ON_REDIRECT``, and ``Retry(allowed_methods=...)``
(Pull 2000) **Starting in urllib3 v2.0: Deprecated options will be removed**
* Added default ``User-Agent`` header to every request (Pull 1750)
* Added ``urllib3.util.SKIP_HEADER`` for skipping ``User-Agent``, ``Accept-Encoding``,
and ``Host`` headers from being automatically emitted with requests (Pull 2018)
* Collapse ``transfer-encoding: chunked`` request data and framing into
the same ``socket.send()`` call (Pull 1906)
* Send ``http/1.1`` ALPN identifier with every TLS handshake by default (Pull 1894)
* Properly terminate SecureTransport connections when CA verification fails (Pull 1977)
* Don't emit an ``SNIMissingWarning`` when passing ``server_hostname=None``
to SecureTransport (Pull 1903)
* Disabled requesting TLSv1.2 session tickets as they weren't being used by urllib3 (Pull 1970)
* Suppress ``BrokenPipeError`` when writing request body after the server
has closed the socket (Pull 1524)
* Wrap ``ssl.SSLError`` that can be raised from reading a socket (e.g. "bad MAC")
into an ``urllib3.exceptions.SSLError`` (Pull 1939)
```
### 1.25.11
```
--------------------
* Fix retry backoff time parsed from ``Retry-After`` header when given
in the HTTP date format. The HTTP date was parsed as the local timezone
rather than accounting for the timezone in the HTTP date (typically
UTC) (Pull 1932, Pull 1935, Pull 1938, Pull 1949)
* Fix issue where an error would be raised when the ``SSLKEYLOGFILE``
environment variable was set to the empty string. Now ``SSLContext.keylog_file``
is not set in this situation (Pull 2016)
```
### 1.25.10
```
--------------------
* Added support for ``SSLKEYLOGFILE`` environment variable for
logging TLS session keys with use with programs like
Wireshark for decrypting captured web traffic (Pull 1867)
* Fixed loading of SecureTransport libraries on macOS Big Sur
due to the new dynamic linker cache (Pull 1905)
* Collapse chunked request bodies data and framing into one
call to ``send()`` to reduce the number of TCP packets by 2-4x (Pull 1906)
* Don't insert ``None`` into ``ConnectionPool`` if the pool
was empty when requesting a connection (Pull 1866)
* Avoid ``hasattr`` call in ``BrotliDecoder.decompress()`` (Pull 1858)
```
### 1.25.9
```
-------------------
* Added ``InvalidProxyConfigurationWarning`` which is raised when
erroneously specifying an HTTPS proxy URL. urllib3 doesn't currently
support connecting to HTTPS proxies but will soon be able to
and we would like users to migrate properly without much breakage.
See `this GitHub issue <https://github.com/urllib3/urllib3/issues/1850>`_
for more information on how to fix your proxy config. (Pull 1851)
* Drain connection after ``PoolManager`` redirect (Pull 1817)
* Ensure ``load_verify_locations`` raises ``SSLError`` for all backends (Pull 1812)
* Rename ``VerifiedHTTPSConnection`` to ``HTTPSConnection`` (Pull 1805)
* Allow the CA certificate data to be passed as a string (Pull 1804)
* Raise ``ValueError`` if method contains control characters (Pull 1800)
* Add ``__repr__`` to ``Timeout`` (Pull 1795)
```
### 1.25.8
```

Changelog
### 20.2.4
```
===================
Deprecations and Removals
-------------------------
- Document that certain removals can be fast tracked. (`8417 <https://github.com/pypa/pip/issues/8417>`_)
- Document that Python versions are generally supported until PyPI usage falls below 5%. (`8927 <https://github.com/pypa/pip/issues/8927>`_)
Features
--------
- New resolver: Avoid accessing indexes when the installed candidate is preferred
and considered good enough. (`8023 <https://github.com/pypa/pip/issues/8023>`_)
- Improve error message friendliness when an environment has packages with
corrupted metadata. (`8676 <https://github.com/pypa/pip/issues/8676>`_)
- Cache package listings on index packages so they are guarenteed to stay stable
during a pip command session. This also improves performance when a index page
is accessed multiple times during the command session. (`8905 <https://github.com/pypa/pip/issues/8905>`_)
- New resolver: Tweak resolution logic to improve user experience when
user-supplied requirements conflict. (`8924 <https://github.com/pypa/pip/issues/8924>`_)
Bug Fixes
---------
- New resolver: Correctly respect ``Requires-Python`` metadata to reject
incompatible packages in ``--no-deps`` mode. (`8758 <https://github.com/pypa/pip/issues/8758>`_)
- New resolver: Pick up hash declarations in constraints files and use them to
filter available distributions. (`8792 <https://github.com/pypa/pip/issues/8792>`_)
- New resolver: If a package appears multiple times in user specification with
different ``--hash`` options, only hashes that present in all specifications
should be allowed. (`8839 <https://github.com/pypa/pip/issues/8839>`_)
Improved Documentation
----------------------
- Add ux documentation (`8807 <https://github.com/pypa/pip/issues/8807>`_)
```
### 20.2.3
```
===================
Deprecations and Removals
-------------------------
- Deprecate support for Python 3.5 (`8181 <https://github.com/pypa/pip/issues/8181>`_)
Features
--------
- Make the ``setup.py install`` deprecation warning less noisy. We warn only
when ``setup.py install`` succeeded and ``setup.py bdist_wheel`` failed, as
situations where both fails are most probably irrelevant to this deprecation. (`8752 <https://github.com/pypa/pip/issues/8752>`_)
```
### 20.2.2
```
===================
Bug Fixes
---------
- Only attempt to use the keyring once and if it fails, don't try again.
This prevents spamming users with several keyring unlock prompts when they
cannot unlock or don't want to do so. (`8090 <https://github.com/pypa/pip/issues/8090>`_)
- Fix regression that distributions in system site-packages are not correctly
found when a virtual environment is configured with ``system-site-packages``
on. (`8695 <https://github.com/pypa/pip/issues/8695>`_)
- Disable caching for range requests, which causes corrupted wheels
when pip tries to obtain metadata using the feature ``fast-deps``. (`8701 <https://github.com/pypa/pip/issues/8701>`_, `8716 <https://github.com/pypa/pip/issues/8716>`_)
- Always use UTF-8 to read ``pyvenv.cfg`` to match the built-in ``venv``. (`8717 <https://github.com/pypa/pip/issues/8717>`_)
- 2020 Resolver: Correctly handle marker evaluation in constraints and exclude
them if their markers do not match the current environment. (`8724 <https://github.com/pypa/pip/issues/8724>`_)
```
### 20.2.1
```
===================
Features
--------
- Ignore require-virtualenv in ``pip list`` (`8603 <https://github.com/pypa/pip/issues/8603>`_)
Bug Fixes
---------
- Correctly find already-installed distributions with dot (``.``) in the name
and uninstall them when needed. (`8645 <https://github.com/pypa/pip/issues/8645>`_)
- Trace a better error message on installation failure due to invalid ``.data``
files in wheels. (`8654 <https://github.com/pypa/pip/issues/8654>`_)
- Fix SVN version detection for alternative SVN distributions. (`8665 <https://github.com/pypa/pip/issues/8665>`_)
- New resolver: Correctly include the base package when specified with extras
in ``--no-deps`` mode. (`8677 <https://github.com/pypa/pip/issues/8677>`_)
- Use UTF-8 to handle ZIP archive entries on Python 2 according to PEP 427, so
non-ASCII paths can be resolved as expected. (`8684 <https://github.com/pypa/pip/issues/8684>`_)
Improved Documentation
----------------------
- Add details on old resolver deprecation and removal to migration documentation. (`8371 <https://github.com/pypa/pip/issues/8371>`_)
- Fix feature flag name in docs. (`8660 <https://github.com/pypa/pip/issues/8660>`_)
```
### 20.2
```
=================
Deprecations and Removals
-------------------------
- Deprecate setup.py-based builds that do not generate an ``.egg-info`` directory. (`6998 <https://github.com/pypa/pip/issues/6998>`_, `8617 <https://github.com/pypa/pip/issues/8617>`_)
- Disallow passing install-location-related arguments in ``--install-options``. (`7309 <https://github.com/pypa/pip/issues/7309>`_)
- Add deprecation warning for invalid requirements format "base>=1.0[extra]" (`8288 <https://github.com/pypa/pip/issues/8288>`_)
- Deprecate legacy setup.py install when building a wheel failed for source
distributions without pyproject.toml (`8368 <https://github.com/pypa/pip/issues/8368>`_)
- Deprecate -b/--build/--build-dir/--build-directory. Its current behaviour is confusing
and breaks in case different versions of the same distribution need to be built during
the resolution process. Using the TMPDIR/TEMP/TMP environment variable, possibly
combined with --no-clean covers known use cases. (`8372 <https://github.com/pypa/pip/issues/8372>`_)
- Remove undocumented and deprecated option ``--always-unzip`` (`8408 <https://github.com/pypa/pip/issues/8408>`_)
Features
--------
- Log debugging information about pip, in ``pip install --verbose``. (`3166 <https://github.com/pypa/pip/issues/3166>`_)
- Refine error messages to avoid showing Python tracebacks when an HTTP error occurs. (`5380 <https://github.com/pypa/pip/issues/5380>`_)
- Install wheel files directly instead of extracting them to a temp directory. (`6030 <https://github.com/pypa/pip/issues/6030>`_)
- Add a beta version of pip's next-generation dependency resolver.
Move pip's new resolver into beta, remove the
``--unstable-feature=resolver`` flag, and enable the
``--use-feature=2020-resolver`` flag. The new resolver is
significantly stricter and more consistent when it receives
incompatible instructions, and reduces support for certain kinds of
:ref:`Constraints Files`, so some workarounds and workflows may
break. More details about how to test and migrate, and how to report
issues, at :ref:`Resolver changes 2020` . Maintainers are preparing to
```
### 20.2b1
```
===================
Bug Fixes
---------
- Correctly treat wheels containing non-ASCII file contents so they can be
installed on Windows. (`5712 <https://github.com/pypa/pip/issues/5712>`_)
- Prompt the user for password if the keyring backend doesn't return one (`7998 <https://github.com/pypa/pip/issues/7998>`_)
Improved Documentation
----------------------
- Add GitHub issue template for reporting when the dependency resolver fails (`8207 <https://github.com/pypa/pip/issues/8207>`_)
```
### 20.1.1
```
===================
Deprecations and Removals

behaviour of copying to a temporary directory. (`7555 <https://github.com/pypa/pip/issues/7555>`_)
- Drop parallelization from ``pip list --outdated``. (`8167 <https://github.com/pypa/pip/issues/8167>`_)
Bug Fixes
---------
- Fix metadata permission issues when umask has the executable bit set. (`8164 <https://github.com/pypa/pip/issues/8164>`_)
- Avoid unnecessary message about the wheel package not being installed
when a wheel would not have been built. Additionally, clarify the message. (`8178 <https://github.com/pypa/pip/issues/8178>`_)
```
### 20.1
```
=================
Process
-------
- Document that pip 21.0 will drop support for Python 2.7.
Features
--------
- Add ``pip cache dir`` to show the cache directory. (`7350 <https://github.com/pypa/pip/issues/7350>`_)
Bug Fixes
---------
- Abort pip cache commands early when cache is disabled. (`8124 <https://github.com/pypa/pip/issues/8124>`_)
- Correctly set permissions on metadata files during wheel installation,
to permit non-privileged users to read from system site-packages. (`8139 <https://github.com/pypa/pip/issues/8139>`_)
```
### 20.1b1
```
===================
Deprecations and Removals
-------------------------
- Remove emails from AUTHORS.txt to prevent usage for spamming, and only populate names in AUTHORS.txt at time of release (`5979 <https://github.com/pypa/pip/issues/5979>`_)
- Remove deprecated ``--skip-requirements-regex`` option. (`7297 <https://github.com/pypa/pip/issues/7297>`_)
- Building of local directories is now done in place, instead of a temporary
location containing a copy of the directory tree. (`7555 <https://github.com/pypa/pip/issues/7555>`_)
- Remove unused ``tests/scripts/test_all_pip.py`` test script and the ``tests/scripts`` folder. (`7680 <https://github.com/pypa/pip/issues/7680>`_)
Features
--------
- pip now implements PEP 610, so ``pip freeze`` has better fidelity
in presence of distributions installed from Direct URL requirements. (`609 <https://github.com/pypa/pip/issues/609>`_)
- Add ``pip cache`` command for inspecting/managing pip's wheel cache. (`6391 <https://github.com/pypa/pip/issues/6391>`_)
- Raise error if ``--user`` and ``--target`` are used together in ``pip install`` (`7249 <https://github.com/pypa/pip/issues/7249>`_)
- Significantly improve performance when ``--find-links`` points to a very large HTML page. (`7729 <https://github.com/pypa/pip/issues/7729>`_)
- Indicate when wheel building is skipped, due to lack of the ``wheel`` package. (`7768 <https://github.com/pypa/pip/issues/7768>`_)
- Change default behaviour to always cache responses from trusted-host source. (`7847 <https://github.com/pypa/pip/issues/7847>`_)
- An alpha version of a new resolver is available via ``--unstable-feature=resolver``. (`988 <https://github.com/pypa/pip/issues/988>`_)
Bug Fixes
---------
- Correctly freeze a VCS editable package when it is nested inside another VCS repository. (`3988 <https://github.com/pypa/pip/issues/3988>`_)
- Correctly handle ``%2F`` in URL parameters to avoid accidentally unescape them
into ``/``. (`6446 <https://github.com/pypa/pip/issues/6446>`_)
- Reject VCS URLs with an empty revision. (`7402 <https://github.com/pypa/pip/issues/7402>`_)
- Warn when an invalid URL is passed with ``--index-url`` (`7430 <https://github.com/pypa/pip/issues/7430>`_)

- Stop failing uninstallation, when trying to remove non-existent files. (`7856 <https://github.com/pypa/pip/issues/7856>`_)
- Prevent an infinite recursion with ``pip wheel`` when ``$TMPDIR`` is within the source directory. (`7872 <https://github.com/pypa/pip/issues/7872>`_)
- Significantly speedup ``pip list --outdated`` by parallelizing index interaction. (`7962 <https://github.com/pypa/pip/issues/7962>`_)
- Improve Windows compatibility when detecting writability in folder. (`8013 <https://github.com/pypa/pip/issues/8013>`_)

- Switch to a dedicated CLI tool for vendoring dependencies.
Deprecations and Removals
-------------------------
- Remove wheel tag calculation from pip and use ``packaging.tags``. This
should provide more tags ordered better than in prior releases. (`6908 <https://github.com/pypa/pip/issues/6908>`_)
- Deprecate setup.py-based builds that do not generate an ``.egg-info`` directory. (`6998 <https://github.com/pypa/pip/issues/6998>`_)
- The pip>=20 wheel cache is not retro-compatible with previous versions. Until
pip 21.0, pip will continue to take advantage of existing legacy cache
entries. (`7296 <https://github.com/pypa/pip/issues/7296>`_)
- Deprecate undocumented ``--skip-requirements-regex`` option. (`7297 <https://github.com/pypa/pip/issues/7297>`_)
- Deprecate passing install-location-related options via ``--install-option``. (`7309 <https://github.com/pypa/pip/issues/7309>`_)
- Use literal "abi3" for wheel tag on CPython 3.x, to align with PEP 384
which only defines it for this platform. (`7327 <https://github.com/pypa/pip/issues/7327>`_)
- Remove interpreter-specific major version tag e.g. ``cp3-none-any``
from consideration. This behavior was not documented strictly, and this
tag in particular is `not useful <https://snarky.ca/the-challenges-in-designing-a-library-for-pep-425/>`_.
Anyone with a use case can create an issue with pypa/packaging. (`7355 <https://github.com/pypa/pip/issues/7355>`_)
- Wheel processing no longer permits wheels containing more than one top-level
.dist-info directory. (`7487 <https://github.com/pypa/pip/issues/7487>`_)
- Support for the ``git+git`` form of VCS requirement is being deprecated and
will be removed in pip 21.0. Switch to ``git+https://`` or
``git+ssh://``. ``git+git://`` also works but its use is discouraged as it is
insecure. (`7543 <https://github.com/pypa/pip/issues/7543>`_)
Features
--------
- Default to doing a user install (as if ``--user`` was passed) when the main
site-packages directory is not writeable and user site-packages are enabled. (`1668 <https://github.com/pypa/pip/issues/1668>`_)
- Warn if a path in PATH starts with tilde during ``pip install``. (`6414 <https://github.com/pypa/pip/issues/6414>`_)
- Cache wheels built from Git requirements that are considered immutable,
because they point to a commit hash. (`6640 <https://github.com/pypa/pip/issues/6640>`_)
- Add option ``--no-python-version-warning`` to silence warnings
related to deprecation of Python versions. (`6673 <https://github.com/pypa/pip/issues/6673>`_)
- Cache wheels that ``pip wheel`` built locally, matching what
``pip install`` does. This particularly helps performance in workflows where
``pip wheel`` is used for `building before installing
<https://pip.pypa.io/en/stable/user_guide/installing-from-local-packages>`_.
Users desiring the original behavior can use ``pip wheel --no-cache-dir``. (`6852 <https://github.com/pypa/pip/issues/6852>`_)
- Display CA information in ``pip debug``. (`7146 <https://github.com/pypa/pip/issues/7146>`_)
- Show only the filename (instead of full URL), when downloading from PyPI. (`7225 <https://github.com/pypa/pip/issues/7225>`_)
- Suggest a more robust command to upgrade pip itself to avoid confusion when the
current pip command is not available as ``pip``. (`7376 <https://github.com/pypa/pip/issues/7376>`_)
- Define all old pip console script entrypoints to prevent import issues in
stale wrapper scripts. (`7498 <https://github.com/pypa/pip/issues/7498>`_)
- The build step of ``pip wheel`` now builds all wheels to a cache first,
then copies them to the wheel directory all at once.
Before, it built them to a temporary directory and moved
them to the wheel directory one by one. (`7517 <https://github.com/pypa/pip/issues/7517>`_)
- Expand ``~`` prefix to user directory in path options, configs, and
environment variables. Values that may be either URL or path are not
currently supported, to avoid ambiguity:
* ``--find-links``
* ``--constraint``, ``-c``
* ``--requirement``, ``-r``
* ``--editable``, ``-e`` (`980 <https://github.com/pypa/pip/issues/980>`_)
Bug Fixes
---------
- Correctly handle system site-packages, in virtual environments created with venv (PEP 405). (`5702 <https://github.com/pypa/pip/issues/5702>`_, `7155 <https://github.com/pypa/pip/issues/7155>`_)
- Fix case sensitive comparison of pip freeze when used with -r option. (`5716 <https://github.com/pypa/pip/issues/5716>`_)
- Enforce PEP 508 requirement format in ``pyproject.toml``
``build-system.requires``. (`6410 <https://github.com/pypa/pip/issues/6410>`_)
- Make ``ensure_dir()`` also ignore ``ENOTEMPTY`` as seen on Windows. (`6426 <https://github.com/pypa/pip/issues/6426>`_)
- Fix building packages which specify ``backend-path`` in pyproject.toml. (`6599 <https://github.com/pypa/pip/issues/6599>`_)
- Do not attempt to run ``setup.py clean`` after a ``pep517`` build error,
since a ``setup.py`` may not exist in that case. (`6642 <https://github.com/pypa/pip/issues/6642>`_)
- Fix passwords being visible in the index-url in
"Downloading <url>" message. (`6783 <https://github.com/pypa/pip/issues/6783>`_)
- Change method from shutil.remove to shutil.rmtree in noxfile.py. (`7191 <https://github.com/pypa/pip/issues/7191>`_)
- Skip running tests which require subversion, when svn isn't installed (`7193 <https://github.com/pypa/pip/issues/7193>`_)
- Fix not sending client certificates when using ``--trusted-host``. (`7207 <https://github.com/pypa/pip/issues/7207>`_)
- Make sure ``pip wheel`` never outputs pure python wheels with a
python implementation tag. Better fix/workaround for
`3025 <https://github.com/pypa/pip/issues/3025>`_ by
using a per-implementation wheel cache instead of caching pure python
wheels with an implementation tag in their name. (`7296 <https://github.com/pypa/pip/issues/7296>`_)
- Include ``subdirectory`` URL fragments in cache keys. (`7333 <https://github.com/pypa/pip/issues/7333>`_)
- Fix typo in warning message when any of ``--build-option``, ``--global-option``
and ``--install-option`` is used in requirements.txt (`7340 <https://github.com/pypa/pip/issues/7340>`_)
- Fix the logging of cached HTTP response shown as downloading. (`7393 <https://github.com/pypa/pip/issues/7393>`_)
- Effectively disable the wheel cache when it is not writable, as is the
case with the http cache. (`7488 <https://github.com/pypa/pip/issues/7488>`_)
- Correctly handle relative cache directory provided via --cache-dir. (`7541 <https://github.com/pypa/pip/issues/7541>`_)

```
### 19.3
```
=================
Deprecations and Removals
-------------------------
- Remove undocumented support for un-prefixed URL requirements pointing

on compatible Linux platforms. The manylinux2014 platform tag definition can
be found in `PEP599 <https://www.python.org/dev/peps/pep-0599/>`_. (`7102 <https://github.com/pypa/pip/issues/7102>`_)
Bug Fixes
---------
- Abort installation if any archive contains a file which would be placed
outside the extraction location. (`3907 <https://github.com/pypa/pip/issues/3907>`_)

``--find-links`` in the text. (`6422 <https://github.com/pypa/pip/issues/6422>`_)
```
### 19.0.3
```
===================
Bug Fixes
---------
- Fix an ``IndexError`` crash when a legacy build of a wheel fails. (`6252 <https://github.com/pypa/pip/issues/6252>`_)
- Fix a regression introduced in 19.0.2 where the filename in a RECORD file
of an installed file would not be updated when installing a wheel. (`6266 <https://github.com/pypa/pip/issues/6266>`_)
```
### 19.0.2
```
===================
Bug Fixes
---------
- Fix a crash where PEP 517-based builds using ``--no-cache-dir`` would fail in
some circumstances with an ``AssertionError`` due to not finalizing a build
directory internally. (`6197 <https://github.com/pypa/pip/issues/6197>`_)
- Provide a better error message if attempting an editable install of a
directory with a ``pyproject.toml`` but no ``setup.py``. (`6170 <https://github.com/pypa/pip/issues/6170>`_)
- The implicit default backend used for projects that provide a ``pyproject.toml``
file without explicitly specifying ``build-backend`` now behaves more like direct
execution of ``setup.py``, and hence should restore compatibility with projects
that were unable to be installed with ``pip`` 19.0. This raised the minimum
required version of ``setuptools`` for such builds to 40.8.0. (`6163 <https://github.com/pypa/pip/issues/6163>`_)
- Allow ``RECORD`` lines with more than three elements, and display a warning. (`6165 <https://github.com/pypa/pip/issues/6165>`_)
- ``AdjacentTempDirectory`` fails on unwritable directory instead of locking up the uninstall command. (`6169 <https://github.com/pypa/pip/issues/6169>`_)
- Make failed uninstalls roll back more reliably and better at avoiding naming conflicts. (`6194 <https://github.com/pypa/pip/issues/6194>`_)
- Ensure the correct wheel file is copied when building PEP 517 distribution is built. (`6196 <https://github.com/pypa/pip/issues/6196>`_)
- The Python 2 end of life warning now only shows on CPython, which is the
implementation that has announced end of life plans. (`6207 <https://github.com/pypa/pip/issues/6207>`_)
Improved Documentation
----------------------
- Re-write README and documentation index (`5815 <https://github.com/pypa/pip/issues/5815>`_)
```
### 19.0.1
```

### 18.1
```
=================
Features
--------
- Allow PEP 508 URL requirements to be used as dependencies.
As a security measure, pip will raise an exception when installing packages from

Changelog
### 3.2 ``` ~~~~~~~~~~~~~~~~ * **SECURITY ISSUE:** Attempted to make RSA PKCS1v1.5 decryption more constant time, to protect against Bleichenbacher vulnerabilities. Due to limitations imposed by our API, we cannot completely mitigate this vulnerability and a future release will contain a new API which is designed to be resilient to these for contexts where it is required. Credit to **Hubert Kario** for reporting the issue. *CVE-2020-25659* * Support for OpenSSL 1.0.2 has been removed. Users on older version of OpenSSL will need to upgrade. * Added basic support for PKCS7 signing (including SMIME) via :class:`~cryptography.hazmat.primitives.serialization.pkcs7.PKCS7SignatureBuilder`. .. _v3-1-1: ``` ### 3.1.1 ``` ~~~~~~~~~~~~~~~~~~ * Updated Windows, macOS, and ``manylinux`` wheels to be compiled with OpenSSL 1.1.1h. .. _v3-1: ``` ### 3.1 ``` ~~~~~~~~~~~~~~~~ * **BACKWARDS INCOMPATIBLE:** Removed support for ``idna`` based :term:`U-label` parsing in various X.509 classes. This support was originally deprecated in version 2.1 and moved to an extra in 2.5. * Deprecated OpenSSL 1.0.2 support. OpenSSL 1.0.2 is no longer supported by the OpenSSL project. The next version of ``cryptography`` will drop support for it. * Deprecated support for Python 3.5. This version sees very little use and will be removed in the next release. * ``backend`` arguments to functions are no longer required and the default backend will automatically be selected if no ``backend`` is provided. * Added initial support for parsing certificates from PKCS7 files with :func:`~cryptography.hazmat.primitives.serialization.pkcs7.load_pem_pkcs7_certificates` and :func:`~cryptography.hazmat.primitives.serialization.pkcs7.load_der_pkcs7_certificates` . * Calling ``update`` or ``update_into`` on :class:`~cryptography.hazmat.primitives.ciphers.CipherContext` with ``data`` longer than 2\ :sup:`31` bytes no longer raises an ``OverflowError``. This also resolves the same issue in :doc:`/fernet`. .. _v3-0: ``` ### 3.0 ``` ~~~~~~~~~~~~~~~~ * **BACKWARDS INCOMPATIBLE:** Removed support for passing an :class:`~cryptography.x509.Extension` instance to :meth:`~cryptography.x509.AuthorityKeyIdentifier.from_issuer_subject_key_identifier`, as per our deprecation policy. * **BACKWARDS INCOMPATIBLE:** Support for LibreSSL 2.7.x, 2.8.x, and 2.9.0 has been removed (2.9.1+ is still supported). * **BACKWARDS INCOMPATIBLE:** Dropped support for macOS 10.9, macOS users must upgrade to 10.10 or newer. * **BACKWARDS INCOMPATIBLE:** RSA :meth:`~cryptography.hazmat.primitives.asymmetric.rsa.generate_private_key` no longer accepts ``public_exponent`` values except 65537 and 3 (the latter for legacy purposes). * **BACKWARDS INCOMPATIBLE:** X.509 certificate parsing now enforces that the ``version`` field contains a valid value, rather than deferring this check until :attr:`~cryptography.x509.Certificate.version` is accessed. * Deprecated support for Python 2. At the time there is no time table for actually dropping support, however we strongly encourage all users to upgrade their Python, as Python 2 no longer receives support from the Python core team. If you have trouble suppressing this warning in tests view the :ref:`FAQ entry addressing this issue <faq-howto-handle-deprecation-warning>`. * Added support for ``OpenSSH`` serialization format for ``ec``, ``ed25519``, ``rsa`` and ``dsa`` private keys: :func:`~cryptography.hazmat.primitives.serialization.load_ssh_private_key` for loading and :attr:`~cryptography.hazmat.primitives.serialization.PrivateFormat.OpenSSH` for writing. * Added support for ``OpenSSH`` certificates to :func:`~cryptography.hazmat.primitives.serialization.load_ssh_public_key`. * Added :meth:`~cryptography.fernet.Fernet.encrypt_at_time` and :meth:`~cryptography.fernet.Fernet.decrypt_at_time` to :class:`~cryptography.fernet.Fernet`. * Added support for the :class:`~cryptography.x509.SubjectInformationAccess` X.509 extension. * Added support for parsing :class:`~cryptography.x509.SignedCertificateTimestamps` in OCSP responses. * Added support for parsing attributes in certificate signing requests via :meth:`~cryptography.x509.CertificateSigningRequest.get_attribute_for_oid`. * Added support for encoding attributes in certificate signing requests via :meth:`~cryptography.x509.CertificateSigningRequestBuilder.add_attribute`. * On OpenSSL 1.1.1d and higher ``cryptography`` now uses OpenSSL's built-in CSPRNG instead of its own OS random engine because these versions of OpenSSL properly reseed on fork. * Added initial support for creating PKCS12 files with :func:`~cryptography.hazmat.primitives.serialization.pkcs12.serialize_key_and_certificates`. .. _v2-9-2: ``` ### 2.9.2 ``` ~~~~~~~~~~~~~~~~~~ * Updated the macOS wheel to fix an issue where it would not run on macOS versions older than 10.15. .. _v2-9-1: ``` ### 2.9.1 ``` ~~~~~~~~~~~~~~~~~~ * Updated Windows, macOS, and ``manylinux`` wheels to be compiled with OpenSSL 1.1.1g. .. _v2-9: ``` ### 2.9 ``` ~~~~~~~~~~~~~~~~ * **BACKWARDS INCOMPATIBLE:** Support for Python 3.4 has been removed due to low usage and maintenance burden. * **BACKWARDS INCOMPATIBLE:** Support for OpenSSL 1.0.1 has been removed. Users on older version of OpenSSL will need to upgrade. * **BACKWARDS INCOMPATIBLE:** Support for LibreSSL 2.6.x has been removed. * Removed support for calling :meth:`~cryptography.hazmat.primitives.asymmetric.x25519.X25519PublicKey.public_bytes` with no arguments, as per our deprecation policy. You must now pass ``encoding`` and ``format``. * **BACKWARDS INCOMPATIBLE:** Reversed the order in which :meth:`~cryptography.x509.Name.rfc4514_string` returns the RDNs as required by :rfc:`4514`. * Updated Windows, macOS, and ``manylinux`` wheels to be compiled with OpenSSL 1.1.1f. * Added support for parsing :attr:`~cryptography.x509.ocsp.OCSPResponse.single_extensions` in an OCSP response. * :class:`~cryptography.x509.NameAttribute` values can now be empty strings. .. _v2-8: ```Links

### 1.26.2 ``` ------------------- * Fixed an issue where ``wrap_socket`` and ``CERT_REQUIRED`` wouldn't be imported properly on Python 2.7.8 and earlier (Pull 2052) ``` ### 1.26.1 ``` ------------------- * Fixed an issue where two ``User-Agent`` headers would be sent if a ``User-Agent`` header key is passed as ``bytes`` (Pull 2047) ``` ### 1.26.0 ``` ------------------- * **NOTE: urllib3 v2.0 will drop support for Python 2**. `Read more in the v2.0 Roadmap <https://urllib3.readthedocs.io/en/latest/v2-roadmap.html>`_. * Added support for HTTPS proxies contacting HTTPS servers (Pull 1923, Pull 1806) * Deprecated negotiating TLSv1 and TLSv1.1 by default. Users that still wish to use TLS earlier than 1.2 without a deprecation warning should opt-in explicitly by setting ``ssl_version=ssl.PROTOCOL_TLSv1_1`` (Pull 2002) **Starting in urllib3 v2.0: Connections that receive a ``DeprecationWarning`` will fail** * Deprecated ``Retry`` options ``Retry.DEFAULT_METHOD_WHITELIST``, ``Retry.DEFAULT_REDIRECT_HEADERS_BLACKLIST`` and ``Retry(method_whitelist=...)`` in favor of ``Retry.DEFAULT_ALLOWED_METHODS``, ``Retry.DEFAULT_REMOVE_HEADERS_ON_REDIRECT``, and ``Retry(allowed_methods=...)`` (Pull 2000) **Starting in urllib3 v2.0: Deprecated options will be removed** * Added default ``User-Agent`` header to every request (Pull 1750) * Added ``urllib3.util.SKIP_HEADER`` for skipping ``User-Agent``, ``Accept-Encoding``, and ``Host`` headers from being automatically emitted with requests (Pull 2018) * Collapse ``transfer-encoding: chunked`` request data and framing into the same ``socket.send()`` call (Pull 1906) * Send ``http/1.1`` ALPN identifier with every TLS handshake by default (Pull 1894) * Properly terminate SecureTransport connections when CA verification fails (Pull 1977) * Don't emit an ``SNIMissingWarning`` when passing ``server_hostname=None`` to SecureTransport (Pull 1903) * Disabled requesting TLSv1.2 session tickets as they weren't being used by urllib3 (Pull 1970) * Suppress ``BrokenPipeError`` when writing request body after the server has closed the socket (Pull 1524) * Wrap ``ssl.SSLError`` that can be raised from reading a socket (e.g. "bad MAC") into an ``urllib3.exceptions.SSLError`` (Pull 1939) ``` ### 1.25.11 ``` -------------------- * Fix retry backoff time parsed from ``Retry-After`` header when given in the HTTP date format. The HTTP date was parsed as the local timezone rather than accounting for the timezone in the HTTP date (typically UTC) (Pull 1932, Pull 1935, Pull 1938, Pull 1949) * Fix issue where an error would be raised when the ``SSLKEYLOGFILE`` environment variable was set to the empty string. Now ``SSLContext.keylog_file`` is not set in this situation (Pull 2016) ``` ### 1.25.10 ``` -------------------- * Added support for ``SSLKEYLOGFILE`` environment variable for logging TLS session keys with use with programs like Wireshark for decrypting captured web traffic (Pull 1867) * Fixed loading of SecureTransport libraries on macOS Big Sur due to the new dynamic linker cache (Pull 1905) * Collapse chunked request bodies data and framing into one call to ``send()`` to reduce the number of TCP packets by 2-4x (Pull 1906) * Don't insert ``None`` into ``ConnectionPool`` if the pool was empty when requesting a connection (Pull 1866) * Avoid ``hasattr`` call in ``BrotliDecoder.decompress()`` (Pull 1858) ``` ### 1.25.9 ``` ------------------- * Added ``InvalidProxyConfigurationWarning`` which is raised when erroneously specifying an HTTPS proxy URL. urllib3 doesn't currently support connecting to HTTPS proxies but will soon be able to and we would like users to migrate properly without much breakage. See `this GitHub issue <https://github.com/urllib3/urllib3/issues/1850>`_ for more information on how to fix your proxy config. (Pull 1851) * Drain connection after ``PoolManager`` redirect (Pull 1817) * Ensure ``load_verify_locations`` raises ``SSLError`` for all backends (Pull 1812) * Rename ``VerifiedHTTPSConnection`` to ``HTTPSConnection`` (Pull 1805) * Allow the CA certificate data to be passed as a string (Pull 1804) * Raise ``ValueError`` if method contains control characters (Pull 1800) * Add ``__repr__`` to ``Timeout`` (Pull 1795) ``` ### 1.25.8 ``` ------------------- * Drop support for EOL Python 3.4 (Pull 1774) * Optimize _encode_invalid_chars (Pull 1787) ```Links

Changelog
### 20.2.4 ``` =================== Deprecations and Removals ------------------------- - Document that certain removals can be fast tracked. (`8417 <https://github.com/pypa/pip/issues/8417>`_) - Document that Python versions are generally supported until PyPI usage falls below 5%. (`8927 <https://github.com/pypa/pip/issues/8927>`_) Features -------- - New resolver: Avoid accessing indexes when the installed candidate is preferred and considered good enough. (`8023 <https://github.com/pypa/pip/issues/8023>`_) - Improve error message friendliness when an environment has packages with corrupted metadata. (`8676 <https://github.com/pypa/pip/issues/8676>`_) - Cache package listings on index packages so they are guarenteed to stay stable during a pip command session. This also improves performance when a index page is accessed multiple times during the command session. (`8905 <https://github.com/pypa/pip/issues/8905>`_) - New resolver: Tweak resolution logic to improve user experience when user-supplied requirements conflict. (`8924 <https://github.com/pypa/pip/issues/8924>`_) Bug Fixes --------- - New resolver: Correctly respect ``Requires-Python`` metadata to reject incompatible packages in ``--no-deps`` mode. (`8758 <https://github.com/pypa/pip/issues/8758>`_) - New resolver: Pick up hash declarations in constraints files and use them to filter available distributions. (`8792 <https://github.com/pypa/pip/issues/8792>`_) - New resolver: If a package appears multiple times in user specification with different ``--hash`` options, only hashes that present in all specifications should be allowed. (`8839 <https://github.com/pypa/pip/issues/8839>`_) Improved Documentation ---------------------- - Add ux documentation (`8807 <https://github.com/pypa/pip/issues/8807>`_) ``` ### 20.2.3 ``` =================== Deprecations and Removals ------------------------- - Deprecate support for Python 3.5 (`8181 <https://github.com/pypa/pip/issues/8181>`_) Features -------- - Make the ``setup.py install`` deprecation warning less noisy. We warn only when ``setup.py install`` succeeded and ``setup.py bdist_wheel`` failed, as situations where both fails are most probably irrelevant to this deprecation. (`8752 <https://github.com/pypa/pip/issues/8752>`_) ``` ### 20.2.2 ``` =================== Bug Fixes --------- - Only attempt to use the keyring once and if it fails, don't try again. This prevents spamming users with several keyring unlock prompts when they cannot unlock or don't want to do so. (`8090 <https://github.com/pypa/pip/issues/8090>`_) - Fix regression that distributions in system site-packages are not correctly found when a virtual environment is configured with ``system-site-packages`` on. (`8695 <https://github.com/pypa/pip/issues/8695>`_) - Disable caching for range requests, which causes corrupted wheels when pip tries to obtain metadata using the feature ``fast-deps``. (`8701 <https://github.com/pypa/pip/issues/8701>`_, `8716 <https://github.com/pypa/pip/issues/8716>`_) - Always use UTF-8 to read ``pyvenv.cfg`` to match the built-in ``venv``. (`8717 <https://github.com/pypa/pip/issues/8717>`_) - 2020 Resolver: Correctly handle marker evaluation in constraints and exclude them if their markers do not match the current environment. (`8724 <https://github.com/pypa/pip/issues/8724>`_) ``` ### 20.2.1 ``` =================== Features -------- - Ignore require-virtualenv in ``pip list`` (`8603 <https://github.com/pypa/pip/issues/8603>`_) Bug Fixes --------- - Correctly find already-installed distributions with dot (``.``) in the name and uninstall them when needed. (`8645 <https://github.com/pypa/pip/issues/8645>`_) - Trace a better error message on installation failure due to invalid ``.data`` files in wheels.

(`8665 <https://github.com/pypa/pip/issues/8665>`_) - New resolver: Correctly include the base package when specified with extras in ``--no-deps`` mode. (`8677 <https://github.com/pypa/pip/issues/8677>`_) - Use UTF-8 to handle ZIP archive entries on Python 2 according to PEP 427, so non-ASCII paths can be resolved as expected. (`8684 <https://github.com/pypa/pip/issues/8684>`_) Improved Documentation ---------------------- - Add details on old resolver deprecation and removal to migration documentation. (`8371 <https://github.com/pypa/pip/issues/8371>`_) - Fix feature flag name in docs. (`8660 <https://github.com/pypa/pip/issues/8660>`_) ``` ### 20.2 ``` ================= Deprecations and Removals ------------------------- - Deprecate setup.py-based builds that do not generate an ``.egg-info`` directory.

Its current behaviour is confusing and breaks in case different versions of the same distribution need to be built during the resolution process. Using the TMPDIR/TEMP/TMP environment variable, possibly combined with --no-clean covers known use cases. (`8372 <https://github.com/pypa/pip/issues/8372>`_) - Remove undocumented and deprecated option ``--always-unzip`` (`8408 <https://github.com/pypa/pip/issues/8408>`_) Features -------- - Log debugging information about pip, in ``pip install --verbose``.

(`6030 <https://github.com/pypa/pip/issues/6030>`_) - Add a beta version of pip's next-generation dependency resolver. Move pip's new resolver into beta, remove the ``--unstable-feature=resolver`` flag, and enable the ``--use-feature=2020-resolver`` flag. The new resolver is significantly stricter and more consistent when it receives incompatible instructions, and reduces support for certain kinds of :ref:`Constraints Files`, so some workarounds and workflows may break. More details about how to test and migrate, and how to report issues, at :ref:`Resolver changes 2020` . Maintainers are preparing to ``` ### 20.2b1 ``` =================== Bug Fixes --------- - Correctly treat wheels containing non-ASCII file contents so they can be installed on Windows. (`5712 <https://github.com/pypa/pip/issues/5712>`_) - Prompt the user for password if the keyring backend doesn't return one (`7998 <https://github.com/pypa/pip/issues/7998>`_) Improved Documentation ---------------------- - Add GitHub issue template for reporting when the dependency resolver fails (`8207 <https://github.com/pypa/pip/issues/8207>`_) ``` ### 20.1.1 ``` =================== Deprecations and Removals ------------------------- - Revert building of local directories in place, restoring the pre-20.1 behaviour of copying to a temporary directory.

(`8167 <https://github.com/pypa/pip/issues/8167>`_) Bug Fixes --------- - Fix metadata permission issues when umask has the executable bit set. (`8164 <https://github.com/pypa/pip/issues/8164>`_) - Avoid unnecessary message about the wheel package not being installed when a wheel would not have been built. Additionally, clarify the message. (`8178 <https://github.com/pypa/pip/issues/8178>`_) ``` ### 20.1 ``` ================= Process ------- - Document that pip 21.0 will drop support for Python 2.7. Features -------- - Add ``pip cache dir`` to show the cache directory. (`7350 <https://github.com/pypa/pip/issues/7350>`_) Bug Fixes --------- - Abort pip cache commands early when cache is disabled. (`8124 <https://github.com/pypa/pip/issues/8124>`_) - Correctly set permissions on metadata files during wheel installation, to permit non-privileged users to read from system site-packages. (`8139 <https://github.com/pypa/pip/issues/8139>`_) ``` ### 20.1b1 ``` =================== Deprecations and Removals ------------------------- - Remove emails from AUTHORS.txt to prevent usage for spamming, and only populate names in AUTHORS.txt at time of release (`5979 <https://github.com/pypa/pip/issues/5979>`_) - Remove deprecated ``--skip-requirements-regex`` option. (`7297 <https://github.com/pypa/pip/issues/7297>`_) - Building of local directories is now done in place, instead of a temporary location containing a copy of the directory tree. (`7555 <https://github.com/pypa/pip/issues/7555>`_) - Remove unused ``tests/scripts/test_all_pip.py`` test script and the ``tests/scripts`` folder. (`7680 <https://github.com/pypa/pip/issues/7680>`_) Features -------- - pip now implements PEP 610, so ``pip freeze`` has better fidelity in presence of distributions installed from Direct URL requirements. (`609 <https://github.com/pypa/pip/issues/609>`_) - Add ``pip cache`` command for inspecting/managing pip's wheel cache. (`6391 <https://github.com/pypa/pip/issues/6391>`_) - Raise error if ``--user`` and ``--target`` are used together in ``pip install`` (`7249 <https://github.com/pypa/pip/issues/7249>`_) - Significantly improve performance when ``--find-links`` points to a very large HTML page. (`7729 <https://github.com/pypa/pip/issues/7729>`_) - Indicate when wheel building is skipped, due to lack of the ``wheel`` package. (`7768 <https://github.com/pypa/pip/issues/7768>`_) - Change default behaviour to always cache responses from trusted-host source. (`7847 <https://github.com/pypa/pip/issues/7847>`_) - An alpha version of a new resolver is available via ``--unstable-feature=resolver``.

(`7621 <https://github.com/pypa/pip/issues/7621>`_) ``` ### 20.0 ``` ================= Process ------- - Switch to a dedicated CLI tool for vendoring dependencies. Deprecations and Removals ------------------------- - Remove wheel tag calculation from pip and use ``packaging.tags``. This should provide more tags ordered better than in prior releases. (`6908 <https://github.com/pypa/pip/issues/6908>`_) - Deprecate setup.py-based builds that do not generate an ``.egg-info`` directory. (`6998 <https://github.com/pypa/pip/issues/6998>`_) - The pip>=20 wheel cache is not retro-compatible with previous versions. Until pip 21.0, pip will continue to take advantage of existing legacy cache entries. (`7296 <https://github.com/pypa/pip/issues/7296>`_) - Deprecate undocumented ``--skip-requirements-regex`` option. (`7297 <https://github.com/pypa/pip/issues/7297>`_) - Deprecate passing install-location-related options via ``--install-option``.

(`7327 <https://github.com/pypa/pip/issues/7327>`_) - Remove interpreter-specific major version tag e.g. ``cp3-none-any`` from consideration. This behavior was not documented strictly, and this tag in particular is `not useful <https://snarky.ca/the-challenges-in-designing-a-library-for-pep-425/>`_. Anyone with a use case can create an issue with pypa/packaging. (`7355 <https://github.com/pypa/pip/issues/7355>`_) - Wheel processing no longer permits wheels containing more than one top-level .dist-info directory. (`7487 <https://github.com/pypa/pip/issues/7487>`_) - Support for the ``git+git`` form of VCS requirement is being deprecated and will be removed in pip 21.0. Switch to ``git+https://`` or ``git+ssh://``. ``git+git://`` also works but its use is discouraged as it is insecure. (`7543 <https://github.com/pypa/pip/issues/7543>`_) Features -------- - Default to doing a user install (as if ``--user`` was passed) when the main site-packages directory is not writeable and user site-packages are enabled.

(`6640 <https://github.com/pypa/pip/issues/6640>`_) - Add option ``--no-python-version-warning`` to silence warnings related to deprecation of Python versions. (`6673 <https://github.com/pypa/pip/issues/6673>`_) - Cache wheels that ``pip wheel`` built locally, matching what ``pip install`` does. This particularly helps performance in workflows where ``pip wheel`` is used for `building before installing <https://pip.pypa.io/en/stable/user_guide/installing-from-local-packages>`_. Users desiring the original behavior can use ``pip wheel --no-cache-dir``. (`6852 <https://github.com/pypa/pip/issues/6852>`_) - Display CA information in ``pip debug``. (`7146 <https://github.com/pypa/pip/issues/7146>`_) - Show only the filename (instead of full URL), when downloading from PyPI.

(`7376 <https://github.com/pypa/pip/issues/7376>`_) - Define all old pip console script entrypoints to prevent import issues in stale wrapper scripts. (`7498 <https://github.com/pypa/pip/issues/7498>`_) - The build step of ``pip wheel`` now builds all wheels to a cache first, then copies them to the wheel directory all at once. Before, it built them to a temporary directory and moved them to the wheel directory one by one. (`7517 <https://github.com/pypa/pip/issues/7517>`_) - Expand ``~`` prefix to user directory in path options, configs, and environment variables. Values that may be either URL or path are not currently supported, to avoid ambiguity: * ``--find-links`` * ``--constraint``, ``-c`` * ``--requirement``, ``-r`` * ``--editable``, ``-e`` (`980 <https://github.com/pypa/pip/issues/980>`_) Bug Fixes --------- - Correctly handle system site-packages, in virtual environments created with venv (PEP 405).

(`6426 <https://github.com/pypa/pip/issues/6426>`_) - Fix building packages which specify ``backend-path`` in pyproject.toml. (`6599 <https://github.com/pypa/pip/issues/6599>`_) - Do not attempt to run ``setup.py clean`` after a ``pep517`` build error, since a ``setup.py`` may not exist in that case. (`6642 <https://github.com/pypa/pip/issues/6642>`_) - Fix passwords being visible in the index-url in "Downloading <url>" message. (`6783 <https://github.com/pypa/pip/issues/6783>`_) - Change method from shutil.remove to shutil.rmtree in noxfile.py.

(`7207 <https://github.com/pypa/pip/issues/7207>`_) - Make sure ``pip wheel`` never outputs pure python wheels with a python implementation tag. Better fix/workaround for `3025 <https://github.com/pypa/pip/issues/3025>`_ by using a per-implementation wheel cache instead of caching pure python wheels with an implementation tag in their name. (`7296 <https://github.com/pypa/pip/issues/7296>`_) - Include ``subdirectory`` URL fragments in cache keys. (`7333 <https://github.com/pypa/pip/issues/7333>`_) - Fix typo in warning message when any of ``--build-option``, ``--global-option`` and ``--install-option`` is used in requirements.txt (`7340 <https://github.com/pypa/pip/issues/7340>`_) - Fix the logging of cached HTTP response shown as downloading. (`7393 <https://github.com/pypa/pip/issues/7393>`_) - Effectively disable the wheel cache when it is not writable, as is the case with the http cache.
